What is a major difference in the extracellular matrix ECM between plant and animal cells?

Answer 1

1) Plant cells have a cell wall as well as a cell membrane, animal cells only have a cell membrane

2) Plant cells have chloroplasts as well as mitochondria, while animal cells only have mitochondria

3) Plant cells tend to be more rectangular shaped and animal cells tend to be more round shaped.

4) Plant cells store glucose in the form of of starch granules and cellulose, animal cells store glucose in the form of glycogen.

Answer 2

Typically, the extracellular matrix of plant cells is made up of a fairly chemically resistant polysaccharide called cellulose. This non-living matrix is rigid and helps plants to maintain their shape based on turgor pressure. For the most part, animals lack an extracellular matrix. However, some animals secrete chitinous, proteinaceous, or calcareous materials that may be used in protection of the animal.

Answer 3

Plant cells have:

Chloroplast

Rectangular

have cell walls

have plastids

Animal cell

No Chloroplast

Round

No Cell Walls

No plastids

Answer 4

Plant cells have a cell wall and chloroplasts, whereas animal cells do not.

Answer 5

Plant ECM is primarily carbohydrate in nature, whereas animal ECM is largely protein based.
